UCD90120A on UCD90AEQ64EVM-650

Other Parts Discussed in Thread: UCD90120, UCD90124, UCD90120A

Hi ,
           We are using UCD90120 in our board and evaluation module what we have is with chip UCD90124.
Initial days I was able to detect the chip UCD90120 using this module. Now it gives the following error and PMBUS_ALERT LED (D13) is glowing.
But still the evaluation board is working fine with UCD90124 which I received with board. Can you please look into this issue?

           For our bulk production pre programming vendor need the file in HEX format. My understanding we have to provide data flash file in Intel HEX format . But HEX file cannot be created in offline mode.

Our current working set up is evaluation module with UCD90124.
Is it possible to generate hex file for UCD90120 using the above combination?
